Now, the payoff: How productive is the average person in the top 20% compared with the average person in the bottom 80% of the planet? Answer this by dividing your answer to question 3c by your answer to question 4b. This chapter and the next are devoted to explaining why this ratio is so large.

The productivity of an average person in the top twenty percent is four (4) times that of an average person in the bottom eighty percent.

Explanation:

In questions 3c and 4b, the values of the gross domestic products for the top twenty (20) percent and the bottom eighty (80) percent are $22,800 and $5,700 respectively. Therefore, if we take the ratio of the two values, we have:

$22800/$5700 = 4

The productivity of an average person in the top twenty percent is four (4) times that of an average person in the bottom eighty percent.

107x106 is the answer
